• W607784413 abstract "Aim of this thesis was to investigate the role of kinship in the occurrence and resolution of reproductive conflicts in eusocial insect societies. Kin theory predicts different strategies on the regulation of worker reproduction in genetically heterogeneous than in homogenous societies. However, a growing number of studies do not meet predictions made by kin theory. While kinship indisputably plays a major role in the evolution of eusocial insect societies, for organisational traits, such as sex allocation, partitioning of reproduction and conflict resolutions, for example punishment or worker reproduction (worker policing), it may be less important. Power held by each individual to enforce its own interest, informational constraints and colony-level performance may be additional factors responsible for the maintenance of social life. By using the model systems of several Temnothorax species and the parthenogenetic ant Platythyrea punctata I investigated these additional factors in the context of worker reproduction. Though predicted by kin theory workers in most Temnothorax species refrain from reproducing in the presence of the queen, but readily produce males from unfertilized eggs in orphaned colonies. In T. unifasciatus, rank relationships exist among workers in queenright colonies. Existing hierarchies influence policing behavior when the colony loses its queen, and observed policing behaviour may often be dominance behavior independent on colony kin structure. As dominance hierarchies are likely disturbed by worker reproduction, existing rank relationships among workers and costly aggressive interactions may be important reasons for the absence of worker reproduction in the presence of a queen. In the clonal ant P. punctata in which policing and dominance behavior is not expected on relatedness grounds, policing individuals that selfishly increase their chance of becoming reproductives later themselves, are most likely the strongest and simultaneously the most fecund individual which would benefit the colony as a whole. Cuticular Hydrocarbons, honestly signalling the state of the worker’s fertility may be an additional reason why workers do not reproduce in queenright colonies. Being recognized and effectively policed by nestmates would lower the incentive for workers to selfishly reproduce in the first place. Queen pheromones, involved in the regulation of worker reproduction may similarly be an honest signal. Workers no longer respond to signals of a queen from distantly related species but respond to queens from a sibling species, which speaks against the rapid evolution of queen pheromones expected from the queen control hypothesis. Colonies appear to be able to raise additional male brood, therefore energy invested in dominance and policing activities due to worker reproduction may constitute the actual cost leading to lower colony performance and presumably explains why workers of most Temnothorax species refrain from reproducing. Kinship theory, so far considered to be of great importance in the occurrence of reproductive conflict and their resolution, appears to play a minor role in the regulation of worker reproduction in ants." @default.
